Abstract:Apolipoprotein E (APOE) is a lipid transporter involved in neural cholesterol metabolism. Highly expressed in astrocytes and microglia, APOE4, one of the three isoforms of the transporter, is a strong genetic risk factor for Alzheimer’s disease, while APOE3 is considered moderate risk and APOE2 protective. Despite recent advances in Alzheimer’s disease research, the exact mechanism by which APOE4 influences the progression of the disease has yet to be determined. One hallmark pathological feature of Alzheimer’… Show more
